If there’s a competition for “sweetest famous siblings,” Prince Michael Jackson and his sister Paris just became the front-runners. While walking the Billboard Music Awards 2017 red carpet on Sunday, Prince Michael spilled details to E! about his and Paris's coordinating yin and yang tattoos, which essentially make the pair two halves of one whole.

When asked about the matching tattoos that he and his sister recently revealed on social media, Prince Michael told E!, “We have one on my other leg of the yin and yang tattoo. So she has the masculine and I have the feminine.” So in addition to honoring each other with their individual body art, the ancient Chinese symbol also seems to symbolize that the famous siblings balance each other out.

Paris shared her thoughts on the sweet ink in an Instagram post back in March, when she and her brother first got them done. “Sometimes I feel like my big brother and I always think the same thoughts, he just doesn’t have a filter and always vocalizes them,” she wrote after defining yin and yang. “Though total opposites, like my gooko and i, the inseparable yin and yang work together finding and causing balance within each other. matchies with my bestie @princejackson!”

Those aren’t the only meaningful tattoos Michael Jackson's two oldest children have. Prince, 20, also told E! about the tributes to his late father that he’s had inked onto his skin. “I have a tattoo of [Jackson’s album] Dangerous on my calf,” he said. “He has the red shirt, the red tie, and the red arm band. I’m also planning a Smooth Criminal tattoo.”

Paris, 19, has also honored her pop star father with a series of tattoos: She has “Queen of my heart” written in Jackson’s handwriting on her wrist, a drawing of his eyes on her forearm, and, most recently, the word Bad (as in, her dad’s 1987 song and album) on her hand. These two are wearing their hearts on their sleeves — and ankles, wrists, and hands.
